PPP adapter copy stopping all network traffic

I'm having a problem with my PPP adapter.

I'm using a USB dial-up 2mb broadband modem which connects perfectly well straight after a reboot. After a while (sometimes a couple of hours) my traffic almost completely stops, although the connection is still good. When i do IPCONFIG in CMD i get 2 copies of the same PPP adapter, one with both the IP address and the Subnet mask having 0.0.0.0. The same adapter appears again underneath with correct addresses, but traffic is limited to 1mb per HOUR. The only way i've found round this is to reboot.

I've tried using different modems and different network cards, but that didn't help.

This has been happening for a while, and i can't find anyone else on google who's had a similar problem.

HELP!!!

Hi mikie,

When i do IPCONFIG in CMD i get 2 copies of the same PPP adapter, one with both the IP address and the Subnet mask having 0.0.0.0. The same adapter appears again underneath with correct addresses, but traffic is limited to 1mb per HOUR.

Could we please see this?

Please goto Start --> Run --> type CMD and press OK --> then type: IPCONFIG /ALL - please post the results here by right-clicking on the Command Prompt window, selecting 'Select All', pressing the Enter key, and then posting on this forum. Alternately, you can save your information to a text file by using the following command: IPCONFIG /ALL > C:\ipconfig.txt -- navigate to that text file, and copy/paste the information from it.

Please goto Start --> Run --> type EVENTVWR and press OK --> Now, look under the System log for any errors and/or warnings. If you find any, please post the relevant heading, along with the details inside by double clicking on the error/warning, and then copy/pasting the information from within.

When your connection becomes slow,what happens if you go to Start --> Run --> type CMD --> press OK. Now type:
  • ipconfig /release -- wait for the connection to release; then
  • ipconfig /renew -- wait for the connection to re-establish, or alternately for an error message to display -- if it is an error message, please post the message.
Please goto Start --> Run --> type msinfo32 and press OK --> Expand Hardware Resources by clicking on the [+] and then select Conflicts/Sharing --> Click on File and then Export.. --> Save it to an easy-to-reach location as conflicts.txt --> Open up that text file, and copy/paste the results into your next reply.

Thanks,
Dan.

Hi Mike,

Just curious, why do you have so many adapters/LAC's installed? I'm assuming that you have actually removed the LAC 8 and LAC 7 NIC's? Did you only install these when testing your connection?

Goto Start --> Programs --> Accessories --> Communications --> Network Connections. In this new screen, could you please either take a Screenshot of the folder, or alternately just tell me everything that is in this folder?

And also, what is it that makes you think that it's the "PPP adapter copy stopping all network traffic"? Any reason why you came to this conclusion? Could it rather be something on your computer interfering with your connection, or are you 100% positive that it's the duplicate post of your PPP adapter causing issues?

Sorry that I don't really have any suggestions to fix this just yet, still trying to get everything set straight in my head.

- Dan

I currently have;

Dialup - disconnected

Internet gateway - connected

LAC7 - connected
LAC8 - disabled

These are my connections as they are right now. i have changed from USB/dialup to ethernet in an attempt to get this sorted. I have found that my ethernet connection is much slower than my USB/dialup connection was, and i may return to the dialup scenario. i'll see what it's like in the morning. the broadband connection isn't connected, that's an old modem that's not connected anymore. (i'm keeping it incase i need to return to it.)

in reply to your questions i have 2 nic's installed - 1 for the ethernet modem and 1 to link my laptop for downloading and filesharing (which is currently disabled to check my ethernet connection tonight).

i think that it's the 'PPP adapter...' that's killing my connection, as after i reboot this duplication corrects itself and i can download normally again. it seems to be the only differential to my system.

i can't be positive about any of this as this isn't my strong area but i would like to add that i've done some searching and i'm looking at the possibility that it's my filesharing software that's the problem somewhere - still looking for more info with that.

I had the BT engineer at my house today too, and he tidied up some of my connections so that may also help somewhere. as i said i'm not sure where the problem is but the only thing i had to start with originally was the duplicate adapters.

as things stand right now my connection is rubbish, my p2p software isn't downloading anything and my internet is intermittent. and also, since i started writing this i've just noticed that the network connection 'internet gateway' has disappeared...... and i've done nothing else!

hopefully these ramblings have helped... :tazz: i'm now considering a fresh install so any help you can give will be appreciated. cheers. mike

Ah, I see.

When you installed both Adapters (one for Internet, one for file-sharing), did you setup the appropriate protocols? If not, what did you do to set these up? Jut stick them in, install the drivers, and then go? I'm guessing that you haven't assigned the appropriate protocols to each NIC, which is resulting in your two Adapters becoming 'confused' and both are trying to do the same task -- which could result in the duplicate PPP entry.

in reply to your questions i have 2 nic's installed - 1 for the ethernet modem and 1 to link my laptop for downloading and filesharing (which is currently disabled to check my ethernet connection tonight).

Did this help? Having the file-sharing NIC disabled..? Did you connection still become extremely choppy/slow?

I had the BT engineer at my house today too, and he tidied up some of my connections so that may also help somewhere. as i said i'm not sure where the problem is but the only thing i had to start with originally was the duplicate adapters.

Could you please post a new ipconfig /all so that I can see what he removed/added, etc.

Thanks,
Dan.

since my last post i have switched back to my USB modem as my ethernet connection was worse than ever. The connection stayed constant but there was less traffic than before.


When you installed both Adapters (one for Internet, one for file-sharing), did you setup the appropriate protocols? If not, what did you do to set these up? Jut stick them in, install the drivers, and then go?

Did this help? Having the file-sharing NIC disabled..? Did you connection still become extremely choppy/slow?



The protocols were fine, there was a bit of confusion when they were both enabled, but i half expected that. they really haven't been both enabled for any length of time - it was purely experimental! as for the speed there was no change - still rubbish.


As i said i have changed back to my USB dial-up modem. I have added a program called 'StayAlive' and i left the computer on again last night to find out if that helped. so far, i have success! It seems that if i don't allow my connection to be cut by my ISP (i'm 99% sure that they're limiting my bandwidth due to running Utorrent and Emule) then there won't be any problem with the modem reconnecting all the time, therefore making it difficult to 'confuse' my connection status.

I currently have 1mb download speeds, which is 10-15 times what i've been having for weeks. the NIC duplication didn't occur last night, and everything is still ok.

I'm not saying that this is fixed, but i do have a bandwidth i'm happier with. it may of course only last until i hit 'add reply' but i'll wait and see.

i'll keep an eye on this, and if there's any change i'll let you know. I do still intend contacting my ISP to shout at them..... :tazz:

:tazz: Well, so much for that!

my 'stay connected' software doesn't keep me connected!

still getting the duplicate adapters, still getting near-zero downloads. the only way to fix it is to reboot.

can this be the work of a nasty isp? am i barking up the wrong tree? is the possibly the work of a virus/trojan or something equally irritating? (i'm using avast, zonealarm, spybot & asquared)

You're not the only one with this problem. I've seen a few instances of people complaining about this since it has plagued me for a while now. I wasn't bothered much until today.

I'm connected thru ADSL Broadband to my ISP which requires a username and password.
When my internet connection has been on for a long time and my ISP suddenly disconnects or times out, the PPP connection does not terminate. When I reconnect, it creates another instance of the PPP adapter. But the browser and everything else tries to connect using the unkilled PPP adapter.
I get the same errors on the IPCONFIG. My only remedy is a reboot at the moment.

This only started happening when i switched my WINXP pro to the other computer and put a WINXP student version on this machine.

Does anyone know how to re-install the PPP adapter for winxp, i've got a small hunch that it might be the problem.
